Anybody here doing sonification with Kyma? If so, can you describe your work?

I don't even know what that is, so I don't know if I do it or not.

Could you explain?

I never heard of it until I bought my Kyma system. As I understand it, sonification means taking non-audio data and transforming it into an audible form. Since people are great at recognizing patterns, complex data may be better understood if sonified.

I find it a cool idea! I've recently gotten into John Cage's ideas of discovering music in ordinary sounds [my paraphrasing]. So I was brainstorming, "What if you could sonify a candle flame? There's a structure and variations in how it burns. Could you base a music composition or improvisation on the sonification? Like how 'bout jammin' with a candle?"

So I thought I'd bring up the topic on the Kyma forum. Beside, it's been TOO quiet lately!

hi Dennis

I to didn't know what sonification was.

I don't know if this counts but something I did many years ago (before I had kyma) was to represent counting binery in musical notes where C was the least sig bit D was the second E was the third and so on. So my little BASIC programme played note groops at 1second intervals as follows C, D, C+D, E, C+E, D+E, C+D+E, F, C+F, D+F etc. It makes a distinctive sound and today when ever I need to count in binary the sound goes through my head and helps me avoid errors.
But an even better byproduct is that out of the mess of notes, your ear picks out a distinctive one note tune. The tune that you hear is defined by the highest note in the groop that was not presant in the previous groop, i.e C, D, C, E, C, D, C, F, C, D, C, E, C, D, C, G, C, D, C, E, C, D, C, F, etc. If you notice that C appears twice as many times as D and D appears twice as many times as E and so on. I have found this to be a very useful sequence in programing where you need to keep a check on eight inputs sequentialy but some are more important than others, but the time delay between each check of any input is compleately regular.

Maybe I've misssed the point but without the use of sound I would never have stumbled apon the sequence.

I've been doing sonification for some time. Mostly of DNA and proteins, but also of just about whatever data set I can find that looks as it might be interesting. My SoftStep algorithmic composing program is set up for both bio and general data, and there is a companion program, DataBin that converts just about any dataset into a MIDI range sequence. SoftStep is a MIDI output program, and of course I use it to drive Kyma - which has become my only synth these days apart from the SoundBlaster which I use as sort of a scratch pad. There is lots of info and music available at my web site on this: http://algoart.com

Cool website, John! Thanks for the information. Likewise, Pete! I've never thought about "hearing" binary sequences, before.

Seems like sonification is mostly an off-line process. I suppose on-line (real-time) sonification overlaps the use of alternative controllers, such as sonifying a dancer's movements, etc. Anybody doing such things?

Well, yes. MIDIdiots have been wiring up dancers for years, for an obvious one. I was doing it as far back as '74 with some Nancy Hauser dancers in Minneapolis. Even got to the Walker with it. Not MIDI then, of course, just sensors taped to the floor, and light beam breakers pretty much like door entry sensors. A guy named Lief Brush was wiring up trees and recording their "EEG's" about the same time. He's still doing it.

The issue with real time sonification of input data is the sensor more than the specific MIDI processing. You need MIDI processing of course but that is easily available with the aforementioned systems. The tough issue is the sensors, what kind to use, how to set them up, etc. There is a little company that has been making cool and relatively inexpensive MIDI-output sensors for several years, and it is the first place I would look to. Their URL is: http://www.infusionsystems.com/
